Text 1A1-I


        Hydrogen is viewed as a promising alternative to fossil fuel, but the methods used to make it either generate too much carbon dioxide or are too expensive. Rice University researchers have found a way to harvest hydrogen from plastic waste using a low-emission method that could more than pay for itself.

           By comparison, “green” hydrogen ⎯ produced using renewable energy sources to split water into its two component elements ⎯ costs roughly US$ 5 for just over two pounds. Though cheaper, most of the nearly 100 million tons of hydrogen used globally in 2022 was derived from fossil fuels, its production generating roughly 12 tons of carbon dioxide per ton of hydrogen.

          The researchers exposed plastic waste samples to rapid flash Joule, bringing their temperature up to 3100 Kelvin. “We demonstrated that we are able to recover up to 68% of that atomic hydrogen as gas with a 94% purity,” Kevin Wyss said. “I hope that this work will allow for the production of clean hydrogen from waste plastics, possibly solving major environmental problems like plastic pollution and the greenhouse gas-intensive production of hydrogen by steam-methane reforming.”

Based on text 1A1-I, judge the following item.



The sentence “‘green’ hydrogen ⎯ produced using renewable energy sources to split water into its two component elements ⎯ costs roughly US$ 5” could be correctly rewritten as the use of renewable energy sources to separate water into its two component elements produces ‘green’ hydrogen, which costs about US$ 5.

The Future Of Accounting:
How Will Digital Transformation Impact Accountants?


     In business, as in life, change is the only true constant. From mitigating unprecedented business disruptors to adapting to new operational paradigms, professionals in all industries find themselves dealing with major changes — many of them driven by emerging technologies.

     Accounting is no exception. The profession has moved far beyond mere bookkeeping and payroll, and like its partner procurement, it’s taking an increasingly strategic role for forward-thinking businesses. While some pundits say accounting has a dim future in the digital world of tomorrow, technologies such as cloud-based data management, process automation and advanced analytics are actually poised to further elevate accountants in new and empowering ways.

     As far back as 2015, industry leaders were sounding the death knell for accountants, convinced emerging technologies — particularly automation — would end in death by digital for accountancy as we know it. And as recently as 2019, accountants surveyed by Robert Half on the impact of automation on their profession expressed concerns about being replaced, having fewer opportunities for creative problem-solving and an overdependence on tech in completing daily tasks.

     Yet, the events between then and now, including the Covid-19 pandemic, have instead shown that accountants, like other professionals, need to worry much more about adaptation than replacement.

     There's no question that digital transformation has radically changed the playing field. Big data has become a rich resource that needs to be tapped to compete effectively. But for businesses ready to leverage the potential of digital tools, this shift is an opportunity, not a threat.

     […]

     Both the skill set and the job description for tomorrow's accountant will be greatly expanded, while still hewing to the core competencies of the profession. Supported by technology in a collaborative setting, accounting teams will be populated with both dedicated accounting professionals and subject matter experts from other areas of the business.

     Tomorrow's accountants may play an advisory role, welcoming business intelligence and procurement professionals and working to chart a strategic sourcing plan. They could leverage data management tools, including augmented reality, to humanize and contextualize spend data for the C-suite to make better decisions based on long-term value rather than return on investment alone.

     With more diverse skill sets and greater technical acumen, accountants can bring their own expertise to teams in other business units, providing crucial financial intelligence, refining budgets or ensuring compliance. […]

     As a function, accounting may become less about refining one's skill set through certifications and more about core competencies that grow over time, with a focus on lifelong education and skill development required to take on a complex, ever-changing business environment.

     Automation and other data-driven technologies are poised to free accountants, not constrain them. Organizations that  understand the potential and importance of these technologies — and invest in the tools and training required to help their accountants take full advantage — will be ahead of the curve. Tomorrow's accountants will play a more creative and strategic role in their companies. As a result, their businesses will not only enjoy more efficient workflows and reap more useful insights from their accounting processes, but help strengthen their own resiliency, agility and competitive footing.

Boy cries Wolf


     After astonishing breakthroughs in artificial intelligence, many people worry that they will end up on the economic scrapheap. Global Google searches for “is my job safe?” have doubled in recent months, as people fear that they will be replaced with large language models (LLMS). Some evidence suggests that widespread disruption is coming. In a recent paper Tyna Eloundou of OpenAI and colleagues say that “around 80% of the US workforce could have at least 10% of their work tasks affected by the introduction of LLMS”. Another paper suggests that legal services, accountancy and travel agencies will face unprecedented upheaval.


     Economists, however, tend to enjoy making predictions about automation more than they enjoy testing them. In the early 2010s many of them loudly predicted that robots would kill jobs by the millions, only to fall silent when employment rates across the rich world rose to all-time highs. Few of the doom-mongers have a good explanation for why countries with the highest rates of tech usage around the globe, such as Japan, Singapore and South Korea, consistently have among the lowest rates of unemployment.


     Here we introduce our first attempt at tracking AI’s impact on jobs. Using American data on employment by occupation, we single out white-collar workers. These include people working in everything from back-office support and financial operations to copy-writers. White-collar roles are thought to be especially vulnerable to generative AI, which is becoming ever better at logical reasoning and creativity.


     However, there is as yet little evidence of an AI hit to employment. In the spring of 2020 white-collar jobs rose as a share of the total, as many people in service occupations lost their job at the start of the covid-19 pandemic. The white-collar share is lower today, as leisure and hospitality have recovered. Yet in the past year the share of employment in professions supposedly at risk from generative AI has risen by half a percentage point.


     It is, of course, early days. Few firms yet use generative-AI tools at scale, so the impact on jobs could merely be delayed. Another possibility, however, is that these new technologies will end up destroying only a small number of roles. While AI may be efficient at some tasks, it may be less good at others, such as management and working out what others need.


     AI could even have a positive effect on jobs. If workers using it become more efficient, profits at their company could rise which would then allow bosses to ramp up hiring. A recent survey by Experis, an IT-recruitment firm, points to this possibility. More than half of Britain’s employers expect AI technologies to have a positive impact on their headcount over the next two years, it finds.


     To see how it all shakes out, we will publish updates to this analysis every few months. But for now, a jobs apocalypse seems a way off.
